Q. Find the derivative of the following function.y=e−8x5Answer: y′=
Identify Function and Rule: Identify the function and the rule to use for differentiation.We have the function y=e−8x5. To find the derivative, we will use the chain rule, which states that the derivative of a composite function is the derivative of the outer function evaluated at the inner function times the derivative of the inner function.
Apply Chain Rule: Apply the chain rule to differentiate the function.The outer function is eu, where u=−8x5. The derivative of eu with respect to u is eu. The inner function is u=−8x5, and its derivative with respect to x is −8×5x5−1=−40x4.
Multiply Derivatives: Multiply the derivatives of the outer and inner functions.The derivative of y with respect to x, denoted as y′, is the product of the derivative of the outer function and the derivative of the inner function. Therefore, y′=e(−8x5)×(−40x4).
Simplify Expression: Simplify the expression for the derivative.y′=−40x4⋅e−8x5This is the simplified form of the derivative.
